Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a building water supply and drainage silencing pipeline. Background Art

[0002] Buildings are a general term for buildings and structures. In order to meet the needs of social life, buildings need to install water supply and drainage systems to supply water to the interior of the buildings. Water supply and drainage systems usually use pipeline transportation, which will produce noise during pipeline transportation.

[0003] In order to reduce the noise generated by the pipeline during the water supply and drainage process, the prior art has made many improvements to the building water supply and drainage pipeline, such as the patent with the publication number CN219734615U, which discloses a special silencer pipeline for building water supply and drainage, including a pipe body, the interior of which is filled and fixed with a filling structure; the pipe body includes a main pipe, the interior of the main pipe shell is provided with a filling hole, the outer side of the main pipe is fixedly connected with an equalizing arm, between the equalizing arms are buried grooves, and the inner wall of the main pipe is fixedly connected with a guide rod; the filling structure includes a filling foam filled and fixed inside the filling hole, and the inner concave surface of the filling foam is evenly provided with sound-absorbing holes. The utility model can use the soil layer and the equalizing arm to distribute and unload the pressure on the top of the pipe body, which can greatly enhance the strength of the pipe body after burial, and improve the life and stability of the pipe body during use, and its silencer component has a simple structure, cheap materials, greatly reduced weight, and is more conducive to the burial of the pipeline.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] In the above-mentioned comparative document, filling foam is arranged inside the pipe body to absorb the noise generated by the water flow through the filling foam, while in the prior art, the water supply and drainage main pipes are basically made of seamless steel pipes. Since seamless steel pipes have strong sealing and pressure resistance, and seamless steel pipes are produced as one-piece molding, it is difficult to retain filling holes and sound-absorbing holes during the production of seamless steel pipes. The filling holes and sound-absorbing holes need to be processed later, and it is relatively difficult to process the filling holes and sound-absorbing holes inside the seamless steel pipes. Therefore, the entire pipe production process is more complicated, which increases the cost of pipe production. Therefore, this field is in urgent need of improving the building water supply and drainage silencer pipes to solve the defects of the prior art. Utility Model Content

[0029] Specific implementation method in this embodiment: the above-mentioned water pipe 1 is a seamless steel pipe, and the partition plate 4 is fixed to the outer side of the water pipe 1 by welding. The number of partition plates 4 is several. After the partition plate 4 is welded, the water pipe 1 is inserted into the protective pipe 2, and one side of the partition plate 4 is tightly against the inner wall of the protective pipe 2 to position the water pipe 1. A baffle 5 is threadedly connected to one end of the water pipe 1, and sound insulation particles are filled in the filling cavity 3 through the other end of the water pipe 1, and the sound insulation particles are compacted. Another baffle 5 is threadedly connected to the other end of the water pipe 1 to seal the sound insulation particles. The overall water supply and drainage pipeline manufacturing method conforms to the existing processing technology, and the manufacturing method is relatively simple. The noise generated by the water flow in the water pipe 1 is silenced by the sound insulation particles. At the same time, the water pipe 1 can be protected by the protective pipe 2 to extend the service life of the water pipe 1.

[0030] When connecting several protection pipes 2, the first sealing ring 14 is embedded in the first arc groove 13, and the quick positioning unit 7 is used to quickly position the ends of adjacent protection pipes 2, and the connecting unit 6 is used to connect and fix the two protection pipes 2. When the connecting unit 6 is connected, the first sealing ring 14 is squeezed to seal the ends of adjacent water pipes 1, thereby improving the efficiency of connection and installation between water supply and drainage pipes.

[0031] It is worth noting that the above-mentioned sound insulation particles include but are not limited to glass fiber wool, polystyrene particles, rock wool or mineral wool, etc., and their selection is determined according to the temperature of the medium transported by the water supply and drainage pipeline or the environment.

[0032] Embodiment 2

[0033] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 This embodiment includes the above-mentioned embodiment, wherein the connecting unit 6 includes a flange ring 8 fixedly connected to the side surface of the end of the protective tube 2, a plurality of mounting holes 9 are penetrated through the flange ring 8, a second arc groove 15 and a third arc groove 17 are opened on one side of the flange ring 8, a second sealing ring 16 is embedded in the second arc groove 15, a sound insulation sealing ring 18 is embedded in the third arc groove 17, and a reinforcing rib 19 is welded between the flange ring 8 and the protective tube 2.

[0034] Specific implementation method in this embodiment: the flange ring 8 is connected to the side surface of the end of the protection tube 2 by later welding. When connecting and installing two adjacent protection tubes 2, the second sealing ring 16 and the sound insulation sealing ring 18 are respectively embedded in the second arc groove 15 and the third arc groove 17, the mounting holes 9 on the two adjacent flange rings 8 are aligned, and the two flange rings 8 are fastened and connected using fasteners.

[0037] Specific implementation method in this embodiment: When connecting and installing two protective tubes 2, first, the plug-in column 12 is inserted into the installation hole 9 at one end of the already fixed protective tube 2, and the side of the support plate 10 is against the side of a flange ring 8. Since the sizes of the flange rings 8 are the same, the flange ring 8 to be connected is directly placed on the two support plates 10. At this time, the two flange rings 8 are in a concentric state. It is only necessary to rotate the flange ring 8 to be fixed to find the position of the installation hole 9 to connect and install the flange rings 8. There is no need for the installer to manually align the two flange rings 8 to the concentric position. At the same time, through the setting of the plug-in column 12, after the two flange rings 8 are aligned and the fasteners in the diagonal position are installed, the plug-in column 12 can be pulled out, and the support plate 10 can be reused, which improves the installation efficiency and reduces the labor intensity of the installer.
